This study explores and conducts an in-depth comparison of the epistemic characteristics in different data types utilized in the science inquiries of preservice teachers regarding noise as a risk in everyday life. Focusing on primary and secondary data in the context of science inquiries about noise, we examined how these data types differ in science inquires in terms of inquiry design, data collection, and analyses. The findings reveal that sensor-based primary data enable direct measurement and observation of key phenomena. Conversely, secondary data rely on predetermined measurement methods within a public data system. These differences require different epistemic considerations during the inquiry process. Based on these findings, we discuss the educational implications concerning teaching approaches for science inquiries, teacher education for inquiry teaching, and the development of risk response competencies in preparation for the VUCA (Volatility, Uncertainty, Complexity, and Ambiguity) era.

This study explored the composition and attributes of modeling instructions and factors of teacher competence in elementary science classes. The study also examined educational research papers regarding modeling instruction cases in elementary schools and elementary teachers' perceptions of modeling instructions using qualitative meta-analysis, which can integrate findings from qualitative research. This investigation led to creating a small group to compose modeling instructions. Furthermore, the modeling approach was demonstrated to go through the process of generating, evaluating, and modifying the model. The attributes of modeling instructions can be divided into factors that affect modeling instructions and competence factors necessary for students participating in modeling instructions. The factors affecting modeling instructions included "small group interactions" and "time limitation in classes." The competence factors necessary for students participating in modeling instructions included "scientific knowledge," "meta-modeling knowledge," and the "ability to control emotions." The teacher competence factors in modeling instructions regarding knowledge, function, and attitude were explored. The teacher competence factors in elementary modeling instructions included "meta-modeling knowledge," "knowledge of modeling assessment," "emotional support for students," and the "awareness of modeling value." Accordingly, this study offered some recommendations for effective modeling instructions.

Considering the importance of spatial thinking in the process of learning astronomy, it is necessary to educate pre-service teachers on teaching methods that consider spatial thinking from the teacher training program stage. Accordingly, after providing education on spatial thinking to pre-service science teachers, problems and improvement plans perceived by them were explored for the images and inquiry activities of astronomy textbook units. In this study, spatial thinking in the astronomical domain was defined as the amalgam of the concepts of space, representation tools, and reasoning processes. The juniors attending the University of Education in the metropolitan area were educated on spatial thinking for two weeks in October 2021. They were then asked to voluntarily select one of the astronomy units to analyze problems in the textbooks and present modification plans to address those problems. Finally, 33 cases presented by 22 pre-service science teachers were analyzed, and the results of the study were as follows. Pre-service teachers recognized the problems in textbooks in terms of the concepts of space and reasoning processes, and proposed improvement plans to supplement them. However, in some cases, even if pre-service teachers properly recognized a problem, the improvement plan was not appropriate, or they were not able to analyze the images or inquiry activities in terms of spatial thinking. This study is significant in that it shows that pre-service teachers have the potential to properly reorganize and revise textbooks by participating in teacher training programs on spatial thinking. Furthermore, based on the results of this study, the direction of the teacher training program concerning spatial thinking was discussed.

The purpose of this study was to find out the factor that causes the difference on understanding the aim and perception of laboratory activities between teachers and students. For this study, in-depth interview was conducted for sixth grade students and teachers of 10 classes. The questionnaire of the interview can be divided into 3 sections: the aim of laboratory activities, whether teachers present the aim of laboratory activities, the method of laboratory class progress and the evaluation method. The factors that bring about the difference between the teachers and the students on perception of the aim are the absence of proper guidance on the aim of laboratory activities, the laboratory classes that the progress out of teachers' intention and evaluation method that is the performed without any relationship with the aim of the laboratory activities. Because the teacher-intended aim of laboratory activities is not properly presented, students can't percept the accurate aim. Even though teachers recognize the importance of the improvement of science process skill acquired through laboratory activities, this is not delivered practically in the class and students also can't percept the importance of science process skill.

The purpose of this study was to investigate secondary science teachers' general perceptions of scientific and creative problem solving. The secondary science teachers responded to a survey. The results indicated that most of the teachers perceived enhancing scientific and creative problem solving skills as one of the most important goals in teaching science. However, they hardly implemented instructions for scientific and creative problem solving in their science lessons. They reported the absence of specialized teaching strategies and assessment tools for scientific and creative problem solving, and university entrance exam-oriented social and educational atmosphere as major barriers. In addition, the teachers tended to present limited understanding of scientific and creative problem solving, which is merely focused on creativity. Considering the results, it was thought that a guide to a clear conception of scientific and creative problem solving was needed. Also, many teaching strategies and appropriate assessment tools for adopting and scientific and creative problem solving were required.

Computer Science has been developed thru the study of information processing, the study of what can be automated, the study of computation, and the study of information processes both natural and artificial. As developing the computer science, the aspect of informatics education was changed. Recently we focus on computational thinking education. In this paper, I review the progress of informatics education and research the applying of unplugged computing as a method of computational thinking education. I also research the considerations about applying of unplugged computing in aspects of teacher preparation, educational content, and teaching resources. As result I found that teachers change their perceptions about computer education, understand the computer science contents, and understand the promotion of students thinking skills in point of view at teacher preparation, that teachers can set the levels of abstraction and can enrich and integrate of contents, and that teacher can manage class time and educational resources preparation in point of view at educational resources.

The KAIE computing system curriculum consists of information equipment, operating systems, and information and communication fields, and covers basic understanding and principles of computer science. The role of the teacher is important to achieve the curriculum achievement standards. Therefore, we examined the factors affecting the teaching capacity of the KAIE computing system curriculum. The results of this study show that the teaching methods of teachers through the literacy of information and communication technology have a statistically significant effect on the teaching competency of the computing system curriculum. Also, male teachers perceived higher perceived factors than female teachers. The differences in teaching competency between teacher groups of less than 5 years and less than 5~10 years were significant. Based on these results, it is necessary to develop collaborate SW teaching strategies and mentor - centered training programs that can strengthen ICT and SW professors' competence and encourage participation of low - career teachers and female teachers.

The purpose of this study was to find out inservice teachers' teaching skills and relevant educational settings that could be applied to an instruction of problem-based learning (PBL). Participants have been instructed PBL teacher training programs and applied PBL into teaching and learning process. Three elementary teachers were selected to participate in the study, and data were collected with semi-structured interviews. The interviews of the teachers in relation to PBL were analyzed by two main topics: (1) the teachers' teaching skills required in PBL and (2) the educational settings in implementing PBL. The results are as follows: First, there is a difficulty involved in the implementation of PBL in that its preparation and teaching process are different from the traditional teaching methodology. However, as a helper who guides the students to self-directed learning in the free and permissible learning environment in which students are motivated to develop their potential effectively, the teachers are to invest their time consistently and to put their efforts into making an effective class in the entire process of PBL. Second, as a method to apply the problem-based learning to the education settings, the teachers must spread the awareness of PBL to fellow teachers, students, their parents and the administrators in education and form the community of the teachers. Most importantly, when the teachers apply PBL in the directly, from the joy of witnessing the changes in the students, they will choose to adopt PBL.

The purpose of this study is to analyze elementary school teachers' perception on application of STEAM education. For this study, a survey was administered to 80 primary teachers. The result showed as follows: First, even though, elementary school teachers have known about the meaning and aims of the STEAM education in detail, they often took a neutral attitude toward the actual teaching method. In addition, they take a negative attitude toward having the gathering. Second, only a few elementary school teachers prepared and used the teaching materials related to the STEAM education in class and teach students the concept based on the STEAM education. Only a few elementary school teachers said that they used the developed modules. However, the demand, developing the modules, was extremely high. This result means that the easy and available modules should be developed to establish the STEAM education. Third, only a few elementary school teachers applied the subject, activity, and estimation related to the STEAM education in actual class. Forth, even though, after applying, there much be the positive affects, most elementary school teachers could not recognize the positive affects. At the same time, elementary school teachers suggested the curriculum should be reorganized for students to connect between the results of the STEAM education and the contents of the textbook, and the easy and available program should be developed and spread, also. The attitude of elementary school teachers toward the application of the STEAM education was normally negative. Therefore, it is needed to include more STEAM related contents in the science textbooks and to develop various STEAM education materials and circulate them as well as to establish adequate teaching and assessment methods for STEAM education.

The purpose of this study was to investigate elementary and middle school teachers' perception and the need for the application of 2015 revised science curriculum. Four hundred and sixty-eight elementary school teachers and four hundred and twenty-two middle school teachers were surveyed. The results of the research are as follows. many elementary and middle school teachers responded that major changes in the 2015 revised curriculum were applicable in school science education. However, they expected that the lack of teaching and learning materials, lack of experiment preparation time, and lack of their understanding about how to improve the scientific core competencies and how to use the content system were major difficulties in applying the major changes in the 2015 revised science curriculum. They also thought that teaching and learning materials were needed in order to apply the 2015 revised science curriculum. Based on these results, this study suggested content for teacher training, the role of teachers, and formation of a teacher community.
